The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();}Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper limit.…
Implement the following tasks by using concepts of object-oriented programming (Java). i. Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…
Write a class called Pokemon that has a name (e.g. “Pikachu”) and a number (e.g. 25). Implement a constructor that takes both values as parameters. Implement accessors for both values. Implement a toString() that returns a string in the format “Name(number)”, e.g. “Pikachu(25)”. Implement an equals(Object) method (two Pokémon are considered equal if they have the same number). Implement a hashCode() method that returns the number.(remember the equals and hashCode contract).
In Java, please. Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9) LabProgram.java import java.util.Scanner; public class LabProgram { public static void main(String args[]) { Scanner scnr = new Scanner(System.in); Course course = new Course(); int…
Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method score() of the parent class to calculate the weighted score for both types of students. Write a driver class JavaProgramming.java which has the main method. Create one remote student object and one in-person student object. The output should show prompts to enter individual scores – midterm, finals, ...... etc. and the program will…

Your implementation should include the following: Fields: MyType[] myBag; int numberofProducts; Default_Capacity; Methods: Constructor(): initialize bag add() - will be used to add a new entry. toArray() - provides an array of the allocated bag. isFull() - test whether the bag is at the maximum capacity. Implement a BagDemo that tests your bag implementation class. Methods: testAddl() - will add the contents to the Bag. displayBag() - will display the contents of the Bag. Please and Thank you
Write a Java program that prompts a user for vehicle data and stores it in a linked list, and then sorts the list in ascending order based on miles-per-gallon and writes the sorted data to a text file, you can follow these steps: Create a class named Vehicle with private fields: make (String), model (String), and milesPerGallon (double). Include getters and setters for these fields. Implement the Comparable interface for Vehicle class and override the compareTo() method to compare vehicles based on their milesPerGallon. Create a main class (for example, VehicleDriver.java) to handle user input and perform the necessary operations. Inside the main method, create a BufferedReader object for user input. Prompt the user to enter the number of vehicle data they want to enter and store it in a variable (for example, nVehicles). Use a loop to iterate nVehicles times and prompt the user to enter make, model, and miles per gallon for each vehicle. Create Vehicle objects using the input data…
*using java* Create a class AnimalCreate a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal(String name) //constructor public void makesSound()with the implementation printing out a generic animal sound. Next, override (add) the makesSound()method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don’t make sounds!)Note, you’ll also need a constructor in each of your subclasses which calls super(name) to initialize the common ‘name’ member of Animal. --- Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. ( you should observe the implementation of the makeSound() method called will be: cat -> from Cat class, dog-> from Dog class,…
1. Write a java class called Pokemon that has a name (e.g. “Pikachu”) and a number (e.g. 25). Implement a constructor that takes both values as parameters. Implement accessors for both values. Implement a toString() that returns a string in the format “Name(number)”, e.g. “Pikachu(25)”. Implement an equals(Object) method (two Pokémon are considered equal if they have the same number). Implement a hashCode() method that returns the number. (remember the equals and hashCode contract). 2. Create a java class, PokemonComparator, that implements Comparator and compares two Pokémon in reverse order by number. For example, if Pokemon A's number is 25 and B's number is 50, compare(A, B) would return a number > 0 because B should come first. Hint: what if you subtracted the numbers? 3. Write a new class, PokemonMain, with a main method that: a. Creates a binary tree with your favorite Pokémon at the root and a new PokemonComparator. b. Insert at least 10-15 more Pokémon in any order. c.…
Write an interface and then modify classes to implement the interface. Write an interface, GeometricSolid, which has one method, volume. The volume method takes no arguments and returns a double. You are provided with three classes: Cylinder, Sphere, and RightCircularCone Modify the classes so that they implement the GeometricSolid interface. Supply the appropriate method for each class. Make sure that you use Math.PI in your calculations. Notice in InterfaceRunner that the objects are added to an ArrayList of GeometricSolids. Cylinder.java /*** Models a Cylinder*/public class Cylinder {private double radius;private double height; /*** Constructor for objects of class Cylinder* @param radius the radius of the Cylinder* @param height the height of this Cylinder*/public Cylinder(double radius, double height){this.radius = radius;this.height = height;}/*** Gets the radius of this Cylinder* @return the radius of the Cylinder*/public double getRadius(){return radius;}/*** Sets the radius of…
Implement the Comparable interface in the Laptop class. When you implement the compareTo() method from the Comparable interface you must use at least two instance variables in the comparison. Once you have implemented the Comparable interface, in the main method: • Add the following comment - // Part 5 - Generic methods • Write the code to sort the Arraylist that you created in Part 4 . • Add the following code - System.out.println("------------------------------");
